All the above-mentioned optional technical solutions can be combined to form optional embodiments of the present disclosure, which are not repeated in the embodiments of the present disclosure.

FIG. 2A is a flowchart of a method for controlling screen brightening according to an exemplary embodiment. As shown in FIG. 2A , the method for controlling brightening screen is used in a terminal, and the method for controlling brightening screen may include the following implementation steps:

In step 201, when the terminal is in a screen-off state, when a first obstruction is detected by the configured distance sensor and the distance between the first obstruction and the screen of the terminal is less than a first preset distance, start the The front camera of the terminal.

The first preset distance may be set by a user according to actual needs, or may be set by default by the terminal, which is not limited in this embodiment of the present disclosure.

In the screen-off state of the terminal, when the configured distance sensor detects the first blocking object and the first blocking area is at a certain distance from the screen of the terminal, it may be that the user's face is close to the screen of the terminal, that is, The first occluder is a human face. However, in a practical application scenario, since the user may also block the distance sensor with his hand when holding the terminal, that is, the first obstruction detected by the distance sensor may also be the user's hand. Therefore, in order to accurately determine whether the user's face is close to the screen of the terminal, that is, to determine whether the user needs to view the screen, the terminal activates the configured front camera.

In step 202, a first image is captured by the front camera, and image processing is performed on the first image.

After starting the front camera, the terminal performs image acquisition through the front camera to obtain a first image. It is not difficult to understand that if the user wants to view the screen, the face of the user is usually facing the screen. Therefore, in order to be able to determine whether the user is viewing the screen, the terminal performs image processing on the collected first image. , to determine whether the first image includes a face image.

It should be noted that, for the specific implementation of the image processing performed by the terminal on the first image, reference may be made to the related art, which is not described in detail in this embodiment of the present disclosure.

In step 203, when it is determined that the first image includes a first face image after image processing, the screen is switched from the screen-off state to the screen-on state.

If it is determined that the first image includes a first face image, it means that the user's face is facing the screen of the terminal, that is, the user may have a need to view the screen of the terminal. Therefore, the terminal switches from the screen-off state. to the bright screen state, thus realizing the bright screen control. In this way, the user can check the content displayed on the screen, for example, check the date, time, etc.

So far, the bright screen control method provided by the embodiments of the present disclosure has been implemented. In addition, in practical application scenarios, users not only need to view the screen, but may also need to use the terminal. However, the terminal is usually locked when the screen is off. Therefore, in order to further improve the user experience, the user can To use the terminal quickly, the embodiment of the present disclosure also provides an automatic unlocking function, and for the specific implementation, please refer to the following steps 204 to 205 .

In step 204, the similarity between the first face image and the pre-stored face verification image is determined.

In a specific implementation, a face verification image is pre-stored in the terminal. Usually, the face verification image is a face image of a user who has permission to use the terminal. For example, the face verification image may be the face verification image of the terminal. The owner's face image (the following is an example for description). That is, before this, the owner of the terminal can use the camera device of the terminal to photograph his own face image, and then store the face image in the terminal as a face verification image.

Of course, the above description is only described by taking the terminal owner's own face image by using the camera device of the terminal as an example. After shooting, the face image obtained by shooting is stored in the terminal through another terminal.

In this way, during the unlocking process, the face verification image can be used to verify the first face image of the unlocking user. Since the first face image may not be the face image of the owner of the terminal, at this time, if the terminal is directly unlocked, certain security risks may exist in the use of the terminal. To this end, the terminal determines the similarity between the first face image and the face verification image to determine whether the first face image is the face image of the owner of the terminal.

It should be noted that, for the specific implementation of determining the similarity between the first face image and the pre-stored face verification image, reference may be made to the related art of image processing, which is not described in detail in this embodiment of the present disclosure.

In step 205, when the similarity between the first face image and the face verification image is greater than or equal to a preset similarity, an unlocking operation is performed.

When the similarity between the first face image and the face verification image is greater than or equal to the preset similarity, it means that the first face image and the face verification image are almost the same. The first face image is the face image of the owner of the terminal, that is, it can be considered that the user corresponding to the first face image has the right to use the terminal, so the terminal can automatically perform the unlocking operation.

In this way, when it is determined that the similarity between the first face image and the face verification image is greater than or equal to the preset similarity, the unlocking operation is automatically performed, avoiding the need for the user to manually unlock, improving the convenience of the operation, and Improved unlocking efficiency.

Further, when the first obstruction is not detected by the distance sensor, and the first face image is not included in the image collected by the front camera, the screen lock operation is performed, and the screen is switched from the bright screen state to The screen-off state.

In a practical application scenario, when the distance sensor does not detect the first obstruction, it does not fully indicate that the user is not using the terminal. For example, when the user lays the terminal on the desktop, the terminal passes the distance sensor. The user may not be detected, but in fact the user may still be looking at the terminal. Therefore, when the first obstruction is not detected by the distance sensor, it can only indicate that the user may not be using the terminal. In order to further accurately determine whether the user is not using the terminal, the terminal needs to use the front camera to capture images , and perform image processing on the collected image to determine whether the image includes the first face image.

That is, when the distance sensor does not detect the first obstruction and the image collected by the front camera does not include the first face image, it is determined that the user is indeed not using the terminal. At this time, in order to save the power consumption of the terminal, the terminal automatically performs a screen-locking operation, and switches the screen-on state to the screen-off state.

In this way, whether the user is currently using the terminal is determined by using the distance sensor to detect the first occluder and the front camera to perform image acquisition, which improves the accuracy of the determination. In addition, when it is detected that no one is using the terminal, the screen is automatically locked and turned off, without requiring manual operation by the user, which improves the convenience of operation, saves power consumption, and improves user experience.

So far, the functions of bright screen control and automatic unlocking of the terminal are realized. In addition, in actual implementation, in some specified application scenarios, the user of the terminal may not want other users to see the content displayed on the current screen. For this reason, the implementation of the present disclosure also provides a function of blurring the displayed content. For its specific implementation, please refer to the following implementation steps.

In step 206, under the specified application scenario, when a second obstruction is detected by the distance sensor and the distance between the second obstruction and the screen of the terminal is less than a second preset distance, the front camera is used A second image is acquired, and image processing is performed on the second image.

The designated application scenario refers to an application scenario that requires privacy protection. For example, the designated application scenario may include but is not limited to an online video chat scenario, an application scenario for viewing private information, and a scenario for using a designated application, wherein the designated application may Pre-specified by the user. That is, in this specified application scenario, the user who is using the terminal may not want other users to see the content currently displayed on the screen. For this reason, when the terminal detects that other users are approaching and watching the screen, it can The content is blurred, and the specific implementation is as follows.

The second preset distance may be set by the user according to actual needs, or may be set by default by the terminal, which is not limited in this embodiment of the present disclosure.

That is, when the terminal detects a second obstruction through the distance sensor and the second obstruction is at a certain distance from the screen of the terminal, the terminal collects the second image through the front camera. Wherein, the front camera may be running in the background, and in this case, the front camera may be re-run at the front end to collect the second image through the front camera.

Similarly, in order to be able to determine whether the second obstruction is the face of another user, the terminal performs image processing on the collected second image to determine whether the collected image includes a second face image, wherein the The second face image is any face image different from the first face image.

For example, please refer to FIG. 2B , the detection distance d in FIG. 2B may refer to the above-mentioned second preset distance, and the area a refers to an image area that can be captured by the front camera 21 . That is, when the terminal detects through the distance sensor 22 that there is a second obstruction entering the area within the distance d, the front camera 21 is used to capture the image of the area a, and then the terminal performs image processing on the captured image, to determine whether the collected image includes the second face image.

In step 207, when it is determined that the second image includes a second face image after image processing, blurring is performed on the content currently displayed on the screen.

When it is determined after image processing that the second image includes a second face image, it indicates that other users are watching the screen of the terminal. At this time, in order to protect the privacy of the user, the terminal performs blur processing on the content currently displayed on the screen. In this way, other users can be prevented from seeing the content currently displayed on the screen, thereby protecting the privacy of the user using the terminal.

In step 208, when the second occluder is not detected by the distance sensor, and the image captured by the front camera does not include the second face image, cancel the blurring of the content currently displayed on the screen .

In the same way as described above, because when the second obstruction is not detected by the distance sensor, it cannot be completely determined that other users are no longer watching the display content of the screen. Therefore, in order to accurately determine whether other users are indeed not watching For the display content of the screen, the terminal also needs to collect images through the front camera, and perform image processing on the collected images. If it is determined after image processing that the captured image does not include the second face image, it is determined that other users are indeed no longer watching the displayed content on the screen. At this time, in order not to delay the normal use of the terminal by the user, the screen can be cancelled. Obfuscation of the currently displayed content.

It should be noted that this is only to cancel the current display on the screen when the distance sensor does not detect the second occluder, and the image captured by the front camera does not include the second face image. The blurring of content will be described as an example. In another embodiment, since the user may not mind other users watching the content currently displayed on the screen, at this time, in order not to delay the normal use of the terminal by the user, the user may manually cancel the terminal's status of the content currently displayed on the screen. Obfuscation.

For example, the terminal may also be provided with an option to cancel the blurring processing. When the user does not need the terminal to perform blurring processing on the currently displayed content, the user can click the canceling blurring processing option to trigger the When the command to cancel the blurring processing is executed, the blurring processing of the content currently displayed on the screen is cancelled.

In this embodiment of the present disclosure, when the terminal is in a screen-off state, when a first obstruction is detected by the configured distance sensor and the distance between the first obstruction and the screen of the terminal is less than the first preset distance, The description may be that the user is close to the screen of the terminal. In order to further determine whether the user needs to view the screen, the front camera of the terminal is activated, and a first image is collected through the front camera. After that, image processing is performed on the first image. If it is determined that the first image includes the first face image after image processing, it means that the user is facing the terminal, that is, the user needs to view the screen. The screen-off state is switched to the screen-on state. In this way, the screen-on-screen control is automatically realized without the need for manual operation by the user, which improves the convenience of operation and improves the efficiency of screen-on-screen control.
